Abstract: tectonics theory development in China less than 100 years, but in this short period of time we see the Chinese geological community's 'Flowers', see China's growing wealth of tectonic theory and prosperity of this paper will combine the world's tectonic theoretical development of the general background, focusing on the geological boundary between China in recent years have several major representative of the views or doctrine, and on China's current development status of tectonic theory, put forward some personal views.

Mid-19th century to the mid-20th century, with industrial development, mineral and human extensively carried out regional geological studies, the geological sciences to a higher stage, and the birth of a study of the lithosphere composition, structure, movement (including deformation and deformation) and the evolution of a very complex branch of geology - Tectonics in the tectonic history of the development of science, there have been many theories, such as the contraction of that balance that gravity, convection, said, pulse that expansion that gravity differentiation that radioactive cycles that oscillate said that radioactive hot melt, etc., why should we continue to develop tectonics theory?
I consider the following reasons: there are many tectonic theory, the perfect place to be, still need to continue to explore and study; tectonics in geology from the important position in the decision, every time a new proposal of tectonic theory often marks the geology into a higher level stage; even, known as plate tectonics in geology made a great revolution. tectonics research and people's production and life closely linked. coal, oil, natural gas, metal ores, and so the energy and mineral exploration will need the guidance of tectonic theory, volcanoes, earthquakes, fall, collapse, etc. very significant threat to human natural disasters, earth movement can not be avoided is the manifestation, tectonics theory only explore the use of that the Earth's internal structure in order to master them to be effective forecasting.

Tectonic theory in the development of China can be divided into three stages: before the 20th century, sporadic, scattered mainland Geological Survey, and in the 19th century to form a 'trough sets theory', known as tectonic theory of Chinese traditional stage; 20 In the early 1940s, represented by Siguang geomechanical theory, known as China's tectonic theory over phase; the early 20th century that 'continental drift hypothesis', in the 1970s formed the theory of plate tectonics the latter half of 20th century The plate theory for improvement and power systems on the Earth's deep exploration.

1 slot sets theory

In 1885, E. Hughes proposed the concept of the platform later stratigraphic thickness of the former Soviet Union, scholars occurrence of small and flat, the crustal movement in order to decrease the overall increase in the area named the main floor .1900, France E. Ogg In his book <<geosyncline and continental blocks>> in, clear the way trough and unify the platform, as a crust on the two basic building blocks. Since then, geosyncline and platform as interrelated theories, integral formed and developed a complete theory, called the ground floor, said slot, referred to as tank units said groove sets the basic point is that the theory of crustal movement is controlled mainly by the vertical movement, horizontal movement is secondary, crustal movement power source within the Earth's gravitational differentiation of material, the material becomes heated causing surface light upward mobility increased uplift, heavier material to sink while cooling down the surface caused by depression.

Mid-20th century, said in a groove on the basis of Taiwan, China older geologists made a thoughtful nature of tectonic theory, they are yellow Jiqing the 'polycyclic tectonic movement, said,' and Chen Da 'to depression theory . '
More than 1.1 cycles of tectonic movements that
Huang JQ 1945, said: geosynclinal development is not a single cycle, but the multi-cycle .50's Huang JQ initially put forward China's deep fracture type, and that the deep fault is multi-cycle activities of .70 years, yellow Jiqing further the theory of polycyclic tectonic movements combined with the theory of plate tectonics, plate movement that is long-term, multi-cycle development.

1.2 to depression theory

The late 1950s, Chen reached that since the Mesozoic crustal evolution entered a new phase, its tectonic nature is a new activity area, from floor area to the active region into the product. Chen up to this new activity area called 'low-lying areas 'It is the development and evolution of continental crust of the third structural units. reveals the development of continental crust, is not as tank units said that it, the only linear stage of development from the ground floor trough stage, but the multi-stage development.

Siguang in the same period China's geologists made a landmark tectonic theory - geomechanics.

2 geomechanics

Geomechanics is a combination of mechanics and geology edge science, mechanics research with tectonic and crustal movements of the causes of science. Geomechanical that a many geological phenomena are the result of crustal movement. 2. Structural features not isolated, but interrelated, mutual restraint, each accompanied by structural features and its students are genetically related group of structural features. crustal movement and explores the origins and sources of power. The main contribution of geomechanics is to clarify the spatial distribution of tectonic law. geomechanics special attention to the transformation of the crust, it is not the various structural features as isolated, fragmentary, accidental, unrelated phenomena, but rather that there are between intrinsic, essential, and regular contact.

3 theory of plate tectonics

Plate tectonics is the rise of the late 1960s, is now the world's most popular tectonic theory it is in continental drift, seafloor spreading theory, based on comprehensive geological study of oceanic and continental data developed from the .70 early, geologist Li C Y. actively introduce our first time with plate plate configuration address system explaining the Qinling Mountains, Qilian tectonic history of the development, over the same period, the tectonic origin of Korean scientists Ren JS, quasi-station 'Huaiyang Shield' included in the Qinling orogenic belt, eastern China made an important amendment to construct into a comprehensive discussion of tectonic evolution of China, the development of a multi-cycle thinking. tectonics scientist Guo Zhi different times to determine the southern trench-arc basin tectonic system, from northwest to southeast from the old to the new development of evolution, for the first time demonstrated the Proterozoic to the South China plate Yangtze plate subduction, collision, crustal growth in southern China to clarify the law.

The current theory of how to use the plate within the plate and on the mainland to reveal the geological history of evolution is still a problem. The driving force on the plate, although the scholars of the many possible ways, but the quest is still in the process. Plate Tectonics continues to improve and develop.

4 Some Reflections

Tectonic theory has experienced 200 years, between progress in this, but also a few detours in my view, any development of the theory of a discipline inseparable from the natural sciences and social sciences as well as to promote the development of other disciplines, any one discipline can not exist alone in the halls of science. Some theories have been replaced a lot of value to explore. Should not be negated, and we are standing on the shoulders of giants to promote the advancement of technology, these have been replaced by the theory is likely that you are looking for a giant. Inseparable from the development of the theory the test of practice, a scientific theory can be called the axiom or abandoned are the result of practice, which requires us to have a spirit of hard work to do geological work and the quality of service to the community.
